Russian Submarines Building.
At the commencement of the war there were nineteen Russian submarines in course of construction. Very little information concerning these boats can be obtained, except that their submerged displacement ranges from 800 to 1,500 tons, and their anticipated surface speed is 20 knots. Some of the 800-ton vessels have already been completed, and the first twelve will be named: Svitza, Leopard, Pantera, Ruis, Kaguar, Tiqr, Yaguar, Vepr, Wolk, Baro, Gepard, and Tur. These vessels have a speed of 16 knots on the surface and 10 knots when submerged. Their complement is 25 officers and men.
CHAPTER V
JAPANESE SUBMARINES
The Imperial Japanese Navy includes a submarine flotilla of seventeen vessels, all except two of which are of the British Holland or Vickers type. Japan commenced the construction of what is now a rapidly increasing and powerful flotilla in 1904 by the purchase of five elementary Holland boats. These, however, are still in the active flotilla and are designated Nos. 1–5. They have a submerged displacement of 120 tons, and are 65 feet in length and 12 feet in beam. Petrol motors of 160 H.-P. drive them at 9 knots on the surface and electric motors of 70 H.-P. at 7 knots when submerged. Their armament consists of one bow expulsion tube with three 18-inch Whitehead torpedoes.
